Lens Shift Range

The examples show the location of the image position in the lens. The lens can be shifted within the shaded area as shown using the normal projection position as a starting point. Note: If lens is shifted in two directions combined, max. range in either direction cannot be obtained due to rounded off area near edge of lens. (Example: shift up and left). See diagrams below:

Lens Option 1: Throw Distance 1.2 - 1.4 x Width of Screen

When only Vertical or only Horizontal Shift is used:

Maximum. Vertical Shift = 60% of screen height (.6 x height)

Maximum Horizontal Shift = 25% of screen width (.25 x width)

Amount of Horizontal Shift when Vertical is @ maximum:

Maximum Horizontal Shift = 5% of screen width (.05 x width)

Amount of Vertical Shift when Horizontal is @ maximum:

Maximum Vertical Shift = 10% of screen height (.10 x height)

Explanation:

•0% shift is when the image center is even with the projector lens center - also known as zero-degree projection-angle

•Shifting beyond the maximum values above will cause image loss in corners or edges

•When Vertical Shift is maximum, Horizontal shift can only be adjusted 5% left or right in example above

•The maximum diagonal movement of the image is expressed as shift in 2 directions, this is the maximum combination of

adjustment (ex. Up & Left, Down & Right, Up & Right, Down & Left)

•Throw distance does not affect image quality

•Lens shift does not affect image quality if within above limits

Example: 56" x 100" Screen TD = 120" to 140" lens to screen

0.60X 56" = 33.6" up or down

0.25X 100" = 25.0" left or right

0.05X 100" = 5.0" left or right

0.10X 56" = 5.6" up or down

90% or 50.4"

40% or 40"

Normal Projection Position

Lens Option 2: Throw Distance 1.4 - 1.77 x Width of Screen
